Slawomir Tulski, data leadership consultant and former Meta data engineering manager, shares his path from geoscience to scaling ads infra. He explains platform versus product specializations. He warns against over-engineering, highlights cloud cost awareness, and discusses which roles are safe from AI. Short, practical takes on hiring, portfolios, and when real-time systems actually matter.

Ruslan Shchuchkin, a GenAI engineer who builds production systems and side projects like Branch GPT. He discusses switching from business to AI engineering. Short takes on building in public, full-stack LLM products, using tools to move fast, starting local AI meetups, and why project track record and product discovery matter more than degrees.

Revathy Ramalingam, senior software and AI engineer who rebuilt her career after a seven-year maternity break, now working in healthcare. She talks about using LLMs to map AI career paths. She explains vibe coding and rapid prototyping with AI tools. She covers RAG pipelines and practical interview tasks to demonstrate skills after a long break.

Aditya Gautam, AI researcher and engineer with experience at Google and Meta, specializing in LLMs, recommender systems and agent architectures. He discusses enterprise adoption hurdles, the economics of fine-tuning versus APIs, agent MLOps needs like guardrails and data lineage, reliability in regulated sectors, designing multi-tenant evals, human-in-the-loop workflows, and the future of multimodal autonomous agents.

Juan Manuel Perafan, analytics engineer and co-author of Fundamentals of Analytics Engineering, shares his journey from psychology to shaping modern data modeling. He discusses the rise of analytics engineering, bridging business and technical teams, dbt and competing tools, Python as the glue, and testing/CI practices to stop silent data failures.

Paul Iusztin, founding AI engineer and author of the LLM Engineer’s Handbook, outlines the full-stack AI engineer skill stack and the shift from proofs-of-concept to shipping production-grade AI. He covers when classical ML beats LLMs, building reliable agentic workflows and knowledge pipelines, using AI assistants as architects, and creating a “Second Brain” portfolio to prove end-to-end engineering value.
